LETTER-NLE.

SPECIFICATION forming part of Letters Patent No. 693,301, dated February 1i, 1902. Application filed December 5, 1901- lSerial No. 84.847. (No model.)

To all whom it may concern:

Beitknown that I, FRANK MCINT'YRE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented a new and useful Improvement in Letter-Files, of which the following is a specification. Y

My invention has relation to letteriiles designed for the temporary holding of lettersV and Fig. 2 is a vertical central section, of the complete article. Fig. 3 is a perspective `view of the device detachedl from its supportingbase. Fig. 4 is a cross-section on line 44, Fig. 2. Y

The device proper is one in which a closelycoiled spiral spring is used asl the letter#v holder, the letters being inserted between the coils or folds of the spring. erally speaking, of the closely-coiled spiral spring A, the standard B, fromwhich the spring is suspended by its upper end, and the controlling-rod O, supported by and adapted to move lengthwise in bearings in the stand-V ard B and connected to the'lower end of the spring, the arrangement being such that when the rod is depressed it will, by reason of its connection with the spring,draw apart or open the coils of the spring sufciently to permit a letter to be inserted or withdrawn from between. The upper end of the rod of course is provided-,as shown, with a suitable head or knob to facilitate its manipulation. The

standard B inthis instanceis tubular, and to its upper end is secured'a laterally-projecting bracket b, in which the top of the spring A is housed and fastened. The rod O iits and is adapted to move up and down in the tubular standard and is connected to the lower end of slide-rod It consists, gen` .the spring by a cross-pin c, which projects laterally from the lower end of the rod through alongitudinal slot ct in the tubular standard B and is soldered or otherwise secured to the base of the spring. The slot a is of length sufficient to permit enough movement to the yC to properly open the coils of thev spring;

l This device as a whole is erected and se; cured upon a suitable base. I prefer for this purpose a base D, having a socket d, in whichl vthelowerend of the standard B is iitted and secured, and a central chamber d', in which the lower end ofthe spring A is housed. There'is between the chamber d' and the socket CZ a communicating longitudinal slot cl2, through which passes the cross-pin c'.

The device as a whole is convenient, eifect;V

ive for the purpose for which'it is intended, and can be made at small cost. V

What I claim herein as new and of my own invention, and desire to secure by Letters Pate ent, is-

l; Aletter-ile, comprisinga standard hav ing a suitable supporting base, a closely;

coiledspiral spring secured atV its upper end to the standard, and a control1ing-rod,con nect'ed at its lower end to the lbase of the spring, and mounted in, and adapted to slide lengthwise in bearin gs in the standard, as and for the purposes hereinbefore s et forth.

2. In a letter-file, a tubular standard, a closely-coiled spiral spring attached at its upper end toa bracket laterally projecting from the upper `end of the standard, a controlling; rod mounted and adapted to slide lengthwise in the tubular standard, and a cross-pin or connectingpiece which is attached to the base of the spring and to the lower end of the rod, and projects through a longitudinal slot inthe standard, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 3d day of December, 1901.

FRANK IVICINTYRE.
